ionic三级目录乃至多级目录如何隐藏tabs？

.directive('hideTabs', function($rootScope) {
    return {
        restrict: 'A',
        link: function(scope, element, attributes) {

            scope.$on('$ionicView.beforeEnter', function() {

                scope.$watch(attributes.hideTabs, function(value){
                    $rootScope.hideTabs = 'tabs-item-hide';
                });

            });

            scope.$on('$ionicView.beforeLeave', function() {
                scope.$watch(attributes.hideTabs, function(value){
                    $rootScope.hideTabs = 'tabs-item-hide';
                });
                scope.$watch('$destroy',function(){
                    $rootScope.hideTabs = false;
                })

            });
        }
    };
})

目前是通过这个指令实现耳机目录的隐藏

这个更强大,不用监听每个页beforeEnter,beforeLeave事件
